Just purchased the Sennheiser HD 439's, which is far and beyond in terms of sound quality over my previously owned cans Koss Porta Pros (gave to brother in law as gift) and Marley Revolution (heavy and sweaty, so I sold them months ago)!! I love the gorgeously balanced sound signature and spacious sound stage driven by my E11, and the comfort! comfort comfort comfort!

Enjoying my Sennheiser CX 215's also. Been using them with my Sony NWZ 474 and a E6 amp!!

1. UE 7 Pro

2. HD 439

3. Sennheiser 215

4. Ultimate Ears 700

5. Sony XBA-1

Not using my UE TF 10's lately, because they are such uncomfortable SOB's when worn for long periods of time...so they are not ranked, but should be.
